Component reuse in structural design: emerging practices and tools for the circular economy

Corentin Jean Dominique Fivet, Pierluigi D'Acunto, Jonas Warmuth, Jan Friedrich Georg Brütting

Structural engineers play an increasing role in ensuring the transition towards a more sustainable construction sector: a) they are responsible for the design of the most resource- and energy-intensive part of buildings and infrastructure, and b) they regu ...

Case-Study on the Creep Behavior of Interconnected Timber Elements using Wood-Wood Connections

Yves Weinand, Julien Gamerro, Martin Thomas Nakad, Jean-François Bocquet

With the increasing use of automation and computer-aided manufacturing in timber construction, a standardized timber construction system using digitally produced wood-wood connections has recently been developed for basic building components. Its structura ...

Comparison of environmental assessment methods when reusing building components: a case study

Corentin Jean Dominique Fivet, Endrit Hoxha, Catherine Elvire L. De Wolf

The building industry is responsible for 35% of all solid waste in Europe and more than a third of greenhouse gas (GHG) emissions. To address this, applying circular economy principles to the building sector is crucial, for example by reusing building elem ...

A Calculation Method for Interconnected Timber Elements Using Wood-Wood Connections

Yves Weinand, Julien Gamerro, Jean-François Bocquet

Wood-wood connections, widely used in the past, have been progressively replaced by steel fasteners in timber constructions. Currently, they can be manufactured and implemented more efficiently thanks to digital fabrication techniques. In addition, with th ...

Development of Novel Standardized Structural Timber Elements Using Wood-Wood Connections

Julien Gamerro

Traditional wood-wood connections, widely used in the past, have been progressively replaced by steel fasteners and bonding processes in modern timber constructions. However, the emergence of digital fabrication and innovative engineered timber products ha ...

Reuse s to xl, A network of hubs for research and resale of second hand architectural components and materials, as an active strategy for sustainability and circular economy

Célia Marine Küpfer

Distinct from recycling, reuse maintains the shape, energy, know-how, technology and cultural part embedded in a component to use it beyond an initial use into a new project without strongly altering it. The "hub" for research and resale of reusable constr ...

Architectural Design Strategies for Building-Integrated Photovoltaics in residential building renovation processes

Sergi Aguacil Moreno

Tomorrow's European cities are already largely built, as much of the existing building stock ¿ with a low level of energy performance ¿ will still be standing in 2050. Urban renewal processes therefore play an essential role towards their sustainable trans ...

Embodied Carbon Benefits of Reusing Structural Components in the Built Environment: a Medium-rise Office Building Case Study

Corentin Jean Dominique Fivet, Jan Friedrich Georg Brütting, Catherine Elvire L. De Wolf

This paper provides parametric estimates of embodied carbon reductions when structural components are reused in a typical office building. First, a lower bound of structural material quantities is estimated for a typical steel frame structure in a low-rise ...

Reuse in Architecture & Structural Design

Jan Friedrich Georg Brütting

Introduction The construction industry has an extensive impact on the global environment and will be facing three big challenges in the next decades: reducing its resource consumption, decreasing its energy use, and limiting its waste production. This is e ...

STRUCTURAL FORM-FINDING FROM RECLAIMED BAR ELEMENTS

Joseph Jean François Desruelle

This thesis applies structural optimization techniques to develop a general methodology for design from reuse. A thorough case study serves as proof-of-concept. Reusing elements from dismantled structures appears as a promising, yet little explored approac ...
